Intramuscular hemangiomas of the digastric muscle are rare. We present the fifth case reported and the second to be imaged in vivo with magnetic resonance imaging. Accurate preoperative diagnosis of these lesions is difficult, but may be facilitated by a high degree of clinical suspicion and imaging. Magnetic resonance imaging using T2-weighted sequencing has been reported to effectively highlight these lesions. We present a case in which magnetic resonance imaging failed to highlight an intramuscular hemangioma of the posterior belly of the digastric muscle. Possible reasons for this failure are discussed.
二腹肌肌内血管瘤较为罕见。我们报告了第五例此类病例，也是第二例通过磁共振成像进行活体成像的病例。对这些病变进行准确的术前诊断较为困难，但高度的临床怀疑和影像学检查可能会有所帮助。据报道，使用T2加权序列的磁共振成像能够有效凸显这些病变。我们呈现了一例磁共振成像未能凸显二腹肌后腹肌内血管瘤的病例，并讨论了出现这种情况的可能原因。
